A number of press agencies reported on the existence of a letter that Iranian President Mahmoud Ahmadinejad addressed to UN Secretary General Ban Ki-Moon on 13 April 2010.

Early dispatches signalled that Iran was requesting a U.N. investigation into the attacks of September 11, 2001, as well as the condemnation of the attacks inside Iran perpetrated by Jundallah, a terrorist organization sponsored by NATO.

However, all that changed when Foreign Policy magazine - belonging to the Brookings Institution - posted on its website a copy of the Iranian letter which made no mention of the 9/11 request, presenting it as the integral version. At that point, most media backpedaled and quickly switched versions.
